GLASSWAB'E.

Application filed May 27, 1914, Serial No. M1294.

To all whom it may concern:

Be it known that 1, WILLIAM P. Parsons, a citizen of the United States of America, and a resident of the city ofCoi-ning, State of New York, have invented certain new and useful Improvements in Glassware, of which the following is a specification.

My invention relates to certain peculiar shaping of the internal contour of a transparent vessel whereby the optical efiect is produced of a vessel which has its external wall in the form of facets or flat faces, whereas, as a matter of fact, such wall may be perfectly smooth and rounded. The utility of this structure will be obvious when it is remembered that external facets, while liable to chip on the corners, are in spite of this objection used on account of the artistic ellect produced thereby.

lVith my improved form the artistic effect is produced and the liability of chipping is obviated, in that there are no c);- ternal angles or projections to be broken away. In addition to this optical ell'ect my shown in the accompanying drawings. produces further optical ell'ccts. as will be hereina'l'ter. described.

Referring to the acconipanyin; drawings, in which corresponding parts are designated by corresponding marks of retorcncc, -l igure l is a plan view of a vessel cover having my inrcnlion applied thereto as the same ap wars to thc Fin". i2 is a side elevation thcrcol, also showing; the optical cll'ect produced. Fig. 3 is a plan view of the cover illustrated optically in Fig. l, but showing merely the external configuration. Fig. l is view made according to the manner in Fig. 2), and in side elevation. Fin. 5 is a horizontal section taken through the cover shown in the above figures on the lines X, X of Fig. 4, and Fig. (3 is a central diamctrical section thcrcoi". I

Referring now to the configuration, it will be noted that in the form of cover Specification of Letters Patent.

interior wall of the cover consists of a series of faces i which, while in vertical section are at a practically uniform distance from the external wall 1, may separate therefrom slightly at the base, as shown, the upper part of the walls terminating in a concave wall 5 which, in the embodiment shown, is within the horizontal planepf the head 3.

Optically, the effect produced by the internal and external configu'ation here described is shown in Figs. 1 and 2, from which it will be seen that in plan and side elevation the article appears to have a series of external faces and that, furthermore, the wall of the central recess appears, clue to retraction in the glass. to be located well llarinp thus described my inventiomwhat 75 I. claim and desire to secure by Letters Patcnt is: i 1

1. new and improved article of manul'acturc of a glass, the exterior wall of which in one cross section-is circular and which in a cross section at right angles is concai'cd and the interior surface of. which in the iirst cross section is polygonal and which in the. other cross section follows substantially the contour of the outer sur- -face.
